Book Closure
The period during which a company closes its shareholder register to determine who is eligible for a dividend, bonus shares, or rights issue. Investors must hold shares before the book closure date to qualify.
01—What is Book Closure?
The definition — and what it means in practice.
Book closure is the period during which a listed company freezes its shareholder register to determine who is entitled to a declared benefit — a cash dividend, bonus shares, a rights issue, or the vote at a general meeting. Whoever is on the register when the books close receives the entitlement, regardless of what happens to the shares afterwards.
Companies announce the closure window (a "from" and "to" date) alongside the corporate action itself, and the exchange publishes it so investors know exactly when eligibility is decided.
Book closure is the cutoff window that decides who gets the dividend: own the shares before it starts, and the payout is yours.
- The register freeze decides entitlement — not who holds the shares on the payment date.
- The practical deadline is the ex-date, which sits just before the closure window begins.
- Trading does NOT stop during book closure; only transfer of registered ownership pauses.
- Closures also occur with no payout at all — purely to fix the voter list for an AGM or EOGM.
02—How book closure works on the PSX
The Pakistan-specific rules, conventions, and numbers.
On the PSX, settlement takes one business day (T+1), so the effective cutoff is the ex-dividend date — buy on or after it and your purchase settles too late to enter the register before the freeze. Every announced closure and its ex-date appears on the exchange's daily notices, which BSL ingests into the ex-dates calendar.
The decisions that trigger closures — results, dividends, bonus issues — are made at board meetings that companies must notify in advance; the board meetings calendar is therefore the early-warning view, and the closure notice is the confirmation.
Expect clusters of closures in reporting seasons, and note that a single company can run a dividend closure and a separate AGM-only closure in the same period — the entitlement column tells them apart.
03—Common misconceptions
Where investors most often get this wrong.
I can't trade the stock while its books are closed.
Trading continues normally through the closure window. What pauses is the registration of ownership transfers — which is exactly why entitlement is fixed by the ex-date, before the window opens.
Buying during book closure still gets me the dividend if I hold until payment.
No — entitlement was decided when the register froze. Buying on or after the ex-date means the seller keeps the payout, however long you hold afterwards.
Every book closure means money is coming.
Many closures carry no payout at all — they exist to fix the shareholder list for an AGM or EOGM vote. Check the entitlement attached to the notice.
04—Using book closure on BSL
Where this term shows up across the platform — with live data.
A live example from the calendar: United Bank Limited goes ex on 31 Jul 2026 (160%) — shares must be owned before that date to receive the entitlement.
- Every upcoming closure, ex-date, and entitlement is listed month-by-month on the PSX ex-dates calendar.
- Watch the decisions form at the board meetings calendar — results and dividend announcements land there first.
- Each stock page's Dividends section shows the book-closure window attached to every recent payout (e.g. FFC).

What investors ask about book closure on the PSX.
Frequently Asked Questions
Before the ex-dividend date. With T+1 settlement, a purchase on or after the ex-date settles too late to enter the register before the books close, so the seller keeps the payout.

Yes — if you were on the register when the books closed, the entitlement is yours even if you sell during or after the window.
A closure held purely to fix the shareholder list for an AGM or EOGM vote — no dividend or bonus attaches to it.
They serve the same purpose. On the PSX the closure is announced as a window; the record date convention used in other markets corresponds to the register cutoff that window creates.
